DRYING DEVICE FOR HOLLOW FIBER MEMBRANE

摘要

The purpose of the present invention is to provide a drying device capable of preventing entanglement of a hollow fiber membrane in a drying chamber and preventing diameter reduction and flattening of the hollow fiber membrane. This drying device comprises the drying chamber having a heating means disposed therein, a guide roll that causes at least two hollow fiber membranes (A) to travel inside the drying chamber, and at least two winding bobbins disposed outside the drying chamber. The drying device simultaneously dries at least two hollow fiber membranes (A) in the drying chamber while winding one hollow fiber membrane (A) on each winding bobbin. A rotation speed control means is attached separately to each of the at least two winding bobbins.
